Is there a good Android app that has also web interface/app to access email accounts mainly Ymail, Gmail, Microsoft Exchange?
I am looking for one that is not blocked by my admin and it also has reliable and fast updated Android app, as ymail for example implement changes all the time and they interrupt their email function.
Ymail app does not accept MS Exchange mails and it is also blocked by my admin.
MS Outlook web app is not blocked but it is very slow using PaleMoon.
Gmail web is also blocked.
Any other proposals?
